I am trying to create an .exe of my python application that I run from the server.py script. I am using Auto-py-to-exe which gives me the following command:

pyinstaller --noconfirm --onedir --console --icon "path" --name "name" --add-data "path" --add-data "path" --add-data "path" --hidden-import "openpyxl.cell._writer " --exclude-module "gevent server.py"  "C:/Users/140476/Documents/57956_EXE_ANALISIS_DATO_TALADRADO/server.py"

Those are my versions:

6067924 INFO: PyInstaller: 6.0.0
6067938 INFO: Python: 3.9.13 (conda)
6067956 INFO: Platform: Windows-10-10.0.19045-SP0
Running auto-py-to-exe v2.40.0

I receive the following error:

6258721 INFO: Loading module hook 'hook-gevent.py' from 'C:\\ProgramData\\Anaconda3\\lib\\site-packages\\PyInstaller\\hooks'...

Any kind of help is welcome, as I have no idea how to deal with this problem. Thank you very much in advance.

Is this due to a specific library? Would be interesting for you to get your script and take parts out to find what is causing this (also called a minimal reproducible example).

I have deleted everything that has to do with pymongo and the database that I mentioned before. The only thing I have added is the multiprocessing library. I have read that the library gives problems with py isntaller. Attached is a piece of code in case someone knows how to help me.

if __name__ == '__main__':
   if sys.platform.startswith('win'):
                # On Windows calling this function is necessary.
       freeze_support()

def interact_callbacks(self):
    @callback(
        Output('add-automatically-button', 'children'),
        Input('add-automatically-button', 'n_clicks')
    )
    def update_output(n_clicks):
        freeze_support()
        if n_clicks is not None:
            print('before process')
            p = Process(target=startInteraction)
            p.start()
            return 'Clicked!'
        else:
            return 'Add automatically'

Thank you very much.

Have you seen these?

If you are running PyInstaller < 3.3, you might need to set Popen.

Yes, I have read them. Apparently if you work with --onedir, you don't need to use popen. Also, I am working with a version higher than 3.3 since I have version 6.

Anyway, I really appreciate your help.

It seems that many people have had this problem years ago but I have not been able to find an answer. It must be related to hook-gevent and the gui. Do you know if anyone has managed to make it work?

Here is a small script demonstrating the multiprocessing library that worked for me after packaging:

import multiprocessing

def f(name):
    print('hello', name)

if __name__ == '__main__':
    multiprocessing.freeze_support()  # Important on Windows
    print('start')
    p1 = multiprocessing.Process(target=f, args=('one',))
    p1.start()
    p2 = multiprocessing.Process(target=f, args=('two',))
    p2.start()
    print('pre-join')
    p1.join()
    p2.join()
    print('post-join')
